Library Description

Library contains functions for getting and setting GPIO pin states Library contains function for mode selection Library contains function for SPI transfer operation Library contains function for SPI get register operation Library contains functions for incrementing and decrementing wiper position

Key functions:

  • uint8_t charger12_mode_select( uint8_t mode_select ) - selects device operation mode by setting RST(CHGEN) and PWM(MODE) pins
  • void charger12_spi_increment_wiper( void ) - increments wiper position by sending 8bit increment wiper command
  • void charger12_spi_decrement_wiper( void ) - decrements wiper position by sending 8bit decrement wiper command

Examples description

The application is composed of three sections :

  • System Initialization - Initializes GPIO pins, SPI and LOG modules
  • Application Initialization - Iniztializes SPI driver
  • Application Task - Executes additional functions based on user input
void applicationTask( )
{
    uart_ready = UART_Data_Ready( );

    if (uart_ready == 1)
    {
        uart_char = UART_Read( );

        switch (uart_char)
        {
            case '+' :
            {
                charger12_case_Plus( );
                break;
            }
            case '-' :
            {
                charger12_case_Minus( );
                break;
            }
            case '1' :
            {
                charger12_case_One( );
                break;
            }
            case '2' :
            {
                charger12_case_Two( );
                break;
            }
            case '3' :
            {
                charger12_case_Three( );
                break;
            }
            case '4' :
            {
                charger12_case_Four( );
                break;
            }
            default :
            {
                mikrobus_logWrite( "> Invalid command", _LOG_LINE );
                break;
            }
        }
    }
}

Additional Functions :

  • charger12_case_Plus() - Increments Wiper position
  • charger12_case_Minus() - Decrements Wiper position
  • charger12_case_One() - Selects 1st mode of operation
  • charger12_case_Two() - Selects 2nd mode of operation
  • charger12_case_Three() - Selects 3rd mode of operation
  • charger12_case_Four() - Selects 4th mode of operation

Other mikroE Libraries used in the example:

  • SPI
  • UART
  • Conversions

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
